What it does

Standards Autofix is an agent skill from shopsys/shopsys. Fixes the violations reported by a failed coding-standards check (ecs, phpstan, phplint, twig-lint, markdown, yaml, and the storefront's tsc, biome and knip) by editing the source directly from the check's log, then packages the fixes as fixup! commits targeting the commits that introduced each violation. Used by the GitLab CI job ai:standards-fix; can also be run locally on a branch. It never rewrites existing history — it only appends commits for the author to review and autosquash.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Code quality, CI/CD and Linting and formatting. It works with GitLab and pnpm. The repository describes itself as: Main repository for maintaining Shopsys Platform packages. Open for ISSUES and PULL REQUESTS.

When your agent uses it

  • Tasks that involve Code quality
  • Tasks that involve CI/CD
  • Tasks that involve Linting and formatting

Example prompts

  • “s tsc, biome and knip) by editing the source directly from the check”
  • “Use the standards-autofix skill to fix the violations reported by a failed coding-standards check (ecs, phpstan, phplint, twig-lint, markdown, yaml…”
  • “/standards-autofix”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Extract the violations from the log
  2. Fix them
  3. Package the diff as fixup commits
  4. Summary

What it can do on your machine

Read from SKILL.md and the folder at commit 0514b92. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • pnpm
    • php
    • tsc

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Standards Autofix loads about 2.5k tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 1,439 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~127
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,439 words (~2,494 tokens).

“MINDSET: You are reading a failed standards check and fixing exactly what it reported, by editing files. You cannot run the checks — no containers, no phing, no composer. Your only inputs are the log and the source. That makes…”
